Following metaphase, the cell enters anaphase - the stage of active chromosome movement.
What exactly moves toward the opposite poles during anaphase?
Correct Answer
Sister chromatids pulled apart after centromere division
Explanation
During anaphase, the centromeres (which divided at the end of metaphase) release the two sister chromatids of each chromosome, which are then pulled to opposite poles by the spindle fibers. Each pole therefore receives one complete set of chromosomes - ensuring each daughter cell will be genetically identical to the parent cell.
